html DOM : unable to insertBefore a DL node.

[e michael brandt]

I am frustrated. It appears that one can not use insertBefore to insert
an A node before a DL node. Is that really true?

I *am* able to insert before a <p id="hh"> tag, but not before a <dl
id="hh"> tag.

i am able to do a body.appendChil d with no trouble.

Finally, winIE6 pops an error: 'Invalid argument' at the last snip line
below (FF1.5 fails silently):

A snip from my code:

****
var newA = document.create Element("A");

var refObj=document .getElementById ("hh");

//document.body.a ppendChild(newA ); //works fine
document.body.i nsertBefore(new A,refObj);// winIE6 error: 'Invalid argument'
****

Any ideas why this is happening Is it me? or is there some rule I've
not been able to find?

Thanks for any help.

P.S. Same problem if I use "div1", a div wrapper around the dl node,
instead of body node.

You want/need
if (refObj != null) {
refObj.parentNo de.insertBefore (newA, refObj);
}
You always need to call the DOM methods insertBefore and appendChild on
the parent node you want to append to or insert into.
